To aZZ whom it may concern Be it known that 1, Emma O. STANO IFF; acitizen of the United States, and a resident of Bakersfield, in thecounty of Kern and State'of California "have made certain new and usefulImprovements in Self-Feeders for Hay-Presses and Threshers, of wlnch thefollowing is a specification. I

-My invention relates toimprovements 1n feeding mechanisms, it beingmore particu larlyan improved self feeder applicable, to either a haypress or to a thresher, and it consists. in the constructions,combinations and arrangements herein described and claimed. w

{The foremost object of myinveiition is to provide a self-act1ng feedmechanism elther for hay presses or threshers,jso arranged as toautomatically take care of the material without supervision of anoperator.

'A further object of the invention isto provide an automatic feeder forhay presses and the like embed in means for automatically regulating"the feed. I

Afurther object of: the invention is to provide a novel self-feedingmechanism for hay presses and thelike, for periodically di-- viding thehay or "other material being fed, so'as todeliver quantitiesof uniformpro- POrtions. l I

A further object of the invention is to provide in combination withtheself feeder,

an improved beater or plunger, which has a collapsible side to preventsticking and damaging'iof the. beater should a quantity "of hav or othermaterial become lodged in the throat" on theiidownstroke.

Other objects and advantages will 'appear in the followingspecification, reference being ha'dto the accompanying drawings, 1nwhich a w lFigure 1=1s afslde elevation showing the general arrangementof the improved-mechanism, th1s View showlng the improved self feederand bin operatively associated with 'a conventional form of haypress,

ts the Iiaychiit8zedmp la*pli railit of I drums respectively designated17 -118- and v 8 connected With'the self feedr inease'thl 3O ion 30.;with, a handle 31 on the outside.

pinion 3O meshes with the rack bar 32, which same diameter but the upperdrum" 19 is considerably larger, all of the drums being provided withspikes or teeth 20, the pur pose of which is to feed the hay downwardlyin the chute 8" onto the rearwardly traveling conveyer' 21. This 7conveyer practically 'forms the bottom of the chute 8, and as the hay-is gathered thereon, it is moved rearwardly until it falls off upon thelower reciprocating pusher Take, 22.

. Thislrake comprises a plurality of collapsible teeth 23,'which fallback into the position shown in Fig. 4 on the forward stroke,"but riseinto the erect position on the rearward stroke. QBy the'latter act, thehay discharged on the rake is carried rear wardly, and naturally byfalling over into the; collapsed positions on the forward stroke, theteeth move beneath the mass of hay on the top to gather a new charge tobe forced out of the throat 24 into the nel 25 of the self'feeder 2. j

Returning to the clearing mechanism, the shaft 26 of the lower drum 17,forms the, pivotal mounting of the frame 27 in which the shafts 28,29ofthe remaining drums are journaled. The frame 27 is adjustable back andforth at various angles, the shaft 26 beingthe pivotal point, by meansofa pin- The in turn is suitably connected to the frame 27 at the top. Atriangular f me 33 forms the support both for the-rack ar and pinion.

V v The feed regulator comprises a conveyer 34, with teeth '35, disposedat an angle in operative relationship to the discharge throat 24. Theupper shaft 36, which is the driven shaft of the conveyer, is thepivotal point on which the conveyor and its housing 37 are'movable byvirtue of making adjustments with the handle 38. p I

The lower or entrance end of the housing 37 ends in a toothed cut-offedge 39 which is for the purpose of removing the surplus strata of hayfrom the-mass moved forwardlytow'ard the discharge throat 24 by thepusher rake 22,: causing such surplus to be carried upwardly: in thefeed regulator housing 37 and again discharged on top of the massadjacent to the discharge point of the conveyer 21. The surplus hay isthus kept in'local circulation inside ofthe bin '1,

1 until the mechanism adjusts itself so as to take care of the surplusand feed it in regular order to the haypress. f Anyconnectionsuitablefor the purpose,

' may be employed between the handle 38 and the lower shaft 40 of thefeed regulatorconveyer, the princlpal requirement being the therespective directions of the handle an hay tunfeed regulator. Theadjustments are fixed by means of a quadrant 41, with which a suitabledetent on the handle'38 cooperates.

Mounted near the entrance end of the feed regulator is a presser roller42, which normally assumes the lowermost position shown byvirtue ofits-own weight, but is pressed upwardly and aside against the tension ofthe spring 43,.by the increasing quantity of hay beneath. The purpose ofthe presser roller 42 is to keep the hay from rising too high andconsequently causing an undesirable quantity to enter, the feedthecut-off 39.

The construction of theselfifeede'r' F2.

serted to bolt the two parts together. These angle irons may be madeeither on the inside or outside. p i

As is the case of the rake 22. in Fig. 4, the pusher rake 44 in Fig.--3has collapsible teeth 46, which assume the pendent positions, indicatedin one instancein Fig. '3, on the rearward stroke, butcollapseinto theregulator at substantially horizontal positionson the forward stroke. Bythese actionsthe hay is moved rearwardly in the tunnel 25. 7

One of the teeth 46' is shown in detail in Fig. .6; Here, one bar 47 ofaplurality of such rake bars, is shown to be provided with a dividedcasting 48, secured at 49 and provided with rear and frontxstops' 50,51, for limiting the corresponding movements of the tooth 46. The toothitself is pivotally mounted as shown, and terminates. at the other endin a short lug52, which keeps the tooth from pulling out and alsocooperates with a second front stop similar to the stop 51. I

Thefeeri dividing mechanism comprises a front 'rake stop '53 "and amovable'rearrake 54, these being respectively projectable into the haytunnel 25 from the bottom and the top, to act upon the rear- .ward'lymoving mass'of hay. As the plunger 55 of the hay press 3 makes an inwardor compression stroke, the cam ,4'-' carried, thereby, acts onv thetoggle mechanism 56 of the front rake sto'p'53,'to project the latterinto the tunnel 25 from a normally retracted 7 position beneath thebottom.

Suitable guides'57 receive thereciprocating members 58=by which thefront 'rake stops 53 are carried. --.The head-59 of'the lower togglemember 56, is'T-shaped so that the toggle mechanism must follow the highand low portions of the-cam4 andconse 50 should also. be mentioned andobserved that discharge end thereof, is a feeder rake cam of a peculiarconstruction. It is in the nature of a double track, the respectivetracks being on the respective sides for the reception of the endsof theshaft 61 on which the rake teeth'are mounted. The cam 60 compriseshorizontal track portions'62, 63 which merge with the curved portions64, 65. Switches 66, 67 pressed by springs 68 into the normal closedpositions are located at the extreme points of the'cam- 60'and preventthe ends of the shaft 61 from returning into the same horizontal camportion after a stroke has been'completed along that particular portion.In other words, the

switches 66, 67 cause the shaft ends to inove in a continuous path,andthe' shape of the cam itself causes the rear movable rake to performa rearward stroke in the tunnel and the return stroke out of the tunnel.It is by this'means that quantities ofyhay are conveyed rearwardly bythe successive rearward movements of the rake 54. Both rakes, namely, 53and 54, enter the hay in the tunnel 25 at precisely the same moment. Thefront rake stop 58 remains stationary, after, having been thrust in, butthe rear rake 54' moves rearwardly to advance or discharge the quantityof hay thus divided off with the result that equal qu'antitiesof hay areregularly delivered to. the. hopper of the hay press 3.

Operating transversely to the hay press 3, is the reciprocating beateror presser 69, which is suitably actuated by means not dieclosed, andincludes a movable side 70. This movable side is normally pressedoutwardly by one or more spr ngs 71., the purpose of this movable andresiliently mounted side being to preventmutilation of the'feeder in 5case auantit Y of havshould become lod ed between the lower edge of thedischarge throat of'the tunnel 25 and the adjacent edge ofvthe feeder.In'such case, the side 70 gives inwardly to overcome the obstruction. It

the movable rear rake 54" includes 'a rectangular guide frame 7 2 whichincludes suitable bracesYB to ftlielrak'e structure," l/Vhilc performingthe oflices of a guide fo'rthe rake 54, the rectangularwf'rame 72 "alsopermits the reci procating beater' 69 to worlr up and down withoutinterfering ith the; movements of the rake. K v f i I The (iratemechanismt iyh." comprises a crank journaled in sand; including cranks.'76, by means" of which the rakes 22, 44 and '54 are reciprocatedthrough pitman connections standards ing drum 'shaftsl 78,, 79. r becrank Shae is 'driven through sprocket and chain connections at one end,and serves to drive the lower feed regu I lator shaft 40 by sprocket andchain connections 81 at theother end. 7

A chain 82' drives, the lower pivotal shaft,

26 from the shaft'40, and achain 83 drives the intermediate drum l8fromthe shaft 26. Similarly, the upper drum 19 is driven by a chain 84applied to a sprocket on the inter mediate shaft; The conveyer 21 isdriven by a crossed -belt '85, which is appliedto pulleys on theadjacent conveyer and clear- The operation'may be briefly reviewed toadvantage, flay, or other-material to be baled, isloaded onto the rake9;while it is in the lowermost position in Fig. 4; When a load'of asuitable size has been accumulated on the'rake; the cable 12 is pulleduntil the rear ends of the rakestrike the stops 16,

causing the rake to tilt and dump the load into the chute8 wherein thedrums 17, and 19 revolve to clear the chute by feeding the hayrearwardly in the. direction of dis- 7 charge of the bottom conveyer-21.

. The crank shaft 4 being continuously rotatable causes the rake 22 and44 to recip I 1 Y .rocate by virtue of the pitman 7 8, thus mow ing thehay toward thedi'scharge throat 24 and the hay press. Each time. theplunger 7 55 of'the hay press fmakes aminward or compression stroke, the4icarried there-V by," moves the toggle mechanism 56. out wardly andcauses the normally retracted of the frontrake stop 53," the 'movablerear is plunged into the hay tram; above and in continuing its motion,which is now rearward, inthe'hay tunnel 25, causes the hay thus dividedoff to be forwarded to the hopper" of the hay press where it' is presseddown into position by. u reciprocatingmy Obviously,if predator 39 isin'the lowermost position, the'qu'antityf-of' hay discharged will beminimum, the surp'lus bein'g directed: upnrardly in the housing 37 bythe moving conveyer 34 to be returned on top of the mass of hayadjacent""toYthe discharge end of the conveyer 21.
